Hoeffding's inequality
NettetVershynin’s book [14] gives general Hoeffding and Bernstein-type inequalities for sums of indepen-dent sub-Gaussian or sub-exponential random variables. In situations where the bounded difference inequality is used, one would like to have analogous bounds for general functions. In this work we NettetIn probability theory, Hoeffding's inequality provides an upper bound on the probability that the sum of bounded independent random variables deviates from its expected value by more than a certain amount.

Our results relax the usual aperiodicity restriction in the literature, and the explicit upper bounds in the …
NettetSimilar results for Bernstein and Bennet inequalities are available. 3 Bennet Inequality In Bennet inequality, we assume that the variable is upper bounded, and want to estimate its moment generating function using variance information. Lemma 3.1. If X EX 1, then 8 0: lnEe (X ) (e 1)Var(X): where = EX Proof. It suffices to prove the lemma when ...

In probability theory, Hoeffding's inequality provides an upper bound on the probability that the sum of bounded independent random variables deviates from its expected value by more than a certain amount. Hoeffding's inequality was proven by Wassily Hoeffding in 1963. Hoeffding's inequality is a … Se mer Let X1, ..., Xn be independent random variables such that $${\displaystyle a_{i}\leq X_{i}\leq b_{i}}$$ almost surely. Consider the sum of these random variables, $${\displaystyle S_{n}=X_{1}+\cdots +X_{n}.}$$ Se mer The proof of Hoeffding's inequality follows similarly to concentration inequalities like Chernoff bounds. The main difference is the use of Se mer • Concentration inequality – a summary of tail-bounds on random variables. • Hoeffding's lemma Se mer The proof of Hoeffding's inequality can be generalized to any sub-Gaussian distribution. In fact, the main lemma used in the proof, Hoeffding's lemma, implies that bounded random variables are sub-Gaussian. A random variable X is called sub-Gaussian, if Se mer Confidence intervals Hoeffding's inequality can be used to derive confidence intervals. We consider a coin that shows heads with probability p and tails with probability 1 − p. We toss the coin n times, generating n samples Se mer NettetThe right hand side would then be the dirac mass at 0 (as seen in the proof of Hoeffding's inequality). There can't be any other example as that would contradict the hypothesis that $\bar{X}$ is bounded, since
